Summary: Gold Momentum Flow EA is an MQL4 expert advisor for XAUUSD. It uses dual EMA crossover with RSI momentum confirmation and ATR-based stop loss. Suitable for H1 timeframe.




Gold Momentum Flow EA is designed specifically for gold (XAUUSD) to capture medium-term trend movements while managing gold's characteristic volatility spikes. The EA combines dual EMA crossover (fast EMA 12, slow EMA 26) for trend direction, RSI(14) momentum filter to avoid low-momentum fakeouts, and ATR-based dynamic stop loss that widens during high volatility. Each trade includes a trailing stop to lock in profits as the trend develops.

Recommended Timeframe: H1
Trading Logic:
  • Trend Detection: Fast EMA12 crosses above Slow EMA26 for uptrend; opposite for downtrend.

  • Momentum Filter: RSI(14) must be above 50 for long entries or below 50 for short entries.

  • Entry Confirmation: Wait for bar close after crossover with momentum confirmation.

  • Risk Management: Dynamic stop loss at 1.5x ATR, take profit at 3x ATR with trailing stop activation after 1x ATR profit.
